SCALE-BOARD-ROUNDING MACHINE L SPECIFICATION forming part of Letters Patent No. 269,893, dated January 2, 1853,

Application filed March 6,1882. (No model.) I

To alt whom it may concern:

Be it known that l, LORENZO H. SPARKS, of Triumph, in county of Trumbull and State of Ohio, have invented a new and useful Improvement in Scale-Board-Rounding Machines, which improvement is fullyset forth in the following specification and accompanying drawings, in which- Figure 1 is a front elevation of the combined vscale board rounding machine and baling press. Fig. 2 is a top view of same. Fig. 3is a vertical sectional view through line aof Fig. 1. Fig. 4 is a perspective view of the vertically-movable slide containing the trimming-knife. Fig. 5 is a rear view of same. Fig. 6 is a perspective of the follow-boards of the press, showing the manner of binding the scale-boards after beingcut.

The object of my invention is to provide a machine for rounding scale-boards for cheeseboxes.

In the manufacture and handling of cheese it is necessary to provide the cheese-box, both in the bottom and over the cheese, with a thin material of some character, which may be removed and replaced whenever the cheese becomes moldy or when the covering becomes moist, owing to the contact of the cheese. The material now most generally employed for this purpose is thin veneeringor wooden boards. The usual designation of this covering is scale-board. It is necessary that these boards should be made in the form of disks to correspond in size with the boxes in which they are used. WVith the original preparations of these scale-boards the present invention has nothing to do; but it is in reference to the preparation of these boards after being cut into sheets that this has to do, the design being to cut them into disks of various sizes.

To this end I will first describe the manner of constructing the machine, and then its method of operation.

In the accompanyingdrawings, A represents the base of the frame, having a suitable elevated floor, A,as shown. From this base, on opposite sides, two posts, B B, project and are united at the top by a cross-beam, B. A horizental cross-beam, 0, also unites the posts B at a point above the surface of the floor A. On the rear side of this frame-work, on the posts thus described and slightly to one side of the center, is a post, I), projecting upward from the floor A and held rigidly in position by means of the braces D D, extending to the posts B B. One face of this post has agroove, E, and this groove faces a similarly-grooved post, F, which is secured to one of the posts B. The inner surfaces of the posts B which face each other are also provided with grooves G. The frame-work thus constructed receives the operating mechanism, which'will now be described.

At the base of the posts B, beneath the floor A, isa sill or base-plate, H. Socketed in this plate centrally is the lower end of a vertical shaft, I, which shaft projects through and is journaled in the cross-beam 0 above the floor A. Directly above the beam (1 the shaft terminates in a disk, J. At a point between the plate H and beam 0 on the shaft is a pulley, K, by means of which motion may be transmitted to the shaft. the shaft is also designed to transmit motion to the trimming-knife, as will be hereinafter more flly described.

The cross-beam L has suitable tongues, which enter the grooves G of the posts B, and centrally this beam is provided with a screw, M, such as is ordinarilly used in presses. A fellow block or board, N, preferably rounded, is provided for the lowerend of the screw, as shown. The follow-beam L is therefore capable of being elevated or lowered, and the-series of holes in the posts enable the operators to adjust the beam at any point and hold itin position by means of the pins P.

Betweenthe diagonally-disposed posts D F, to the rear of the posts 'B,is a slide, Q, having tongues Q, which enter the grooves E. This slide is provided on its front face with a box or projection, It. A bit, S, having a downwardly-turned point orcutting-edge,is secured to this slide and box by means of a key, T. The cutting-edge of this bit projects forward toward the screw M, as will be hereinafter shown. This slide, it will be observed, is therefore capable of being moved up and down in the guideway thus provided.

To provide for the regular movement of the slide Q to correspond with the velocity of the revolution ofthe shaft I, a screw-threaded shaft,

A similar pulley on r U, socketed in the base-plate V on the lower sill, projects through the box R of the slide Q. On the under side of the box It are two clamping-levers, W, which embrace the screwthreaded shaft U and are also screw-threaded at the points of contact with the shaft. The ends of these clamping-levers project through the slide Q and an arm, Y, hinged to the slide and provided with a gain, Y, serves to keep the clamping-levers tightly compressed on the shaft U when the machine is in operation. The lower end of the shaft U has a pulley, U, to receive motion through the belt I from the shaft I.

The operation will now be described in detail.

The sheets from which the scale-boards are out are placed in a column on the disk J, after which the follow-board N is placed on and the beam L lowered and adjusted and the screw M brought into play, compressing the whole. In case the scale-boards are desired for shipment, a thick board or disk, a, is first placed on the disk J, and a similar one, I), is also placed on the top of the column beneath the follow-board N. The object of this is to pro vide a ready means for binding the column, after it is cut,'before removing it from the press. To accomplish this, metallic or wooden strips 0, one on each side, extend from the disk a to I), and are nailed thereto. hen therefore the pressure of the screw M is removed the baled column can be removed, and is ready for shipment.

The operation of cuttingis as follows: Power is transmitted to the shaft I, causing the column Z, as shown in Fig. 1, to rapidly revolve.

In the meantime the slide Q has ;been raised so that the bitwill be above the column Z, and the bit adjusted or removed to or from the column, so as to cut the size of disk required. The clamping-levers WV are then compressed so as to grasp the threaded-shaft U. This latter shaft being in motion, and the slide connected thereto, the bit travels down the column, cutting the sheets evenly and quickly.

l lavingdescribed my invention, what I claim is 1. In a scale-board-rounding machine, the vertically-disposed revolving shaft I, having the disk Jand the screw M for compressing the column or bale,in combination with the adjustable bit S, secured to the slide Q, vertically movable between the diagonally-dis posed posts D and F, grooved at E, substantially as set forth.

2. In a scale-board-roumling machine, the vertical screw-threaded shaft U, having on its lower end a pulley for receiving motion, the slide Q, arranged angularly, as described, having the clamping-levers W and the cutting-bit S, in combination with mechanism, substantially as described, for compressing, securing, and revolving the scale-board sheets, all substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of February, 1882, in the presence of witnesses.
